Organic electroluminescent device with light-transmissive optical compensation layer
First Claim
1. An organic electroluminescent device (OELD), comprising:
- a substrate;
a transparent anode disposed on the substrate;
a transparent cathode disposed opposite the transparent anode;
an organic light emitting layer interposed between the transparent anode and the transparent cathode;
a first light transmissive optical compensation layer interposed between the transparent anode and the substrate; and
a second light transmissive optical compensation layer disposed on the transparent cathode, wherein at least one of the first light transmissive optical compensation layer and the second light transmissive optical compensation layer comprises WO3, Ta2O3, V2O5, CeO2, Nb2O5, Gd2O3, Cr2O3, NiO, Bi2O3, SmO, Nd2O5 or combinations thereof.

Abstract
An organic electroluminescent device, a flat panel display, and a portable electronic device using the same are disclosed. The organic electroluminescent device comprises a substrate, a transparent anode disposed on the substrate, a transparent cathode disposed opposite the transparent anode, and an organic light emitting layer interposed between the transparent anode and the transparent cathode. The organic electroluminescent device further comprises a first light transmissive optical compensation layer interposed between the transparent anode and the substrate, wherein the first light transmissive optical compensation layer is substantially made of a transition metal oxide.
